These samples extend the editor of TX Text Control .NET for Windows Forms: styles and tables of contents, line numbers and watermarks, lists and tables, zooming, printing and data binding. Each is a small project on GitHub that shows one technique around the [TextControl](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/reference/txtextcontrol/textcontrol/llms-full.txt), with a blog article that explains it. The tables name the version and the framework each project references today; the code itself often dates from the year of the article.

### Before You Run an Older Sample

Most of these samples are projects for the .NET Framework that reference the TX Text Control assemblies of your installation, and some reference an earlier version. Add the references again from the *Assembly* folder of your installation and update the version in *licenses.licx*, as [GitHub Examples](https://docs.textcontrol.com/tx-text-control-dotnet-winforms/examples/github/#update-an-older-sample) describes. All samples are in C# unless the table says Visual Basic.
